REMOVABLE CAP ATTACHMENT.

Application filed November 11, 1927. /Seria1 No. 232,618.

has for its principal object to provide attaching means for the cap to prevent the loss of 4 the same when the cap is removed or detached from the tube.

Another object is to providea cap attachment which may be easily and quickly sprung on or off either the cap or nozzle and is rotatably secured to both of'such members, or may be arranged to yieldably grip the cap Whereby to enable the rotation of both the cap and the attachment during the removal of the cap from the tube.

Another object is to form the attachement from a single strand of spring-like wire having one end thereof formed into a loop adapted to fit over the nozzle of the tube while the opposite end is formed into a cap gripping member, the intermediate sections of the wire being formed into a spring whereby to urge the cap into closed position with respect to the nozzle.

A still further object is to provide an attachment of this character of simple and practical construction, enabling the cap to be easily and quickly removed from the tube, which is inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages of the invention reside in the special construction and V combination of the various elements forming the invention, reference being had to the accompanying drawings, wherein Figure 1 is a view in side elevation showing the attachment in posit'on with respect to a tube and cap, and,

Figure 2 is a perspective View thereof.

Referring now to the drawing in detail, I provide a removable cap attachment comprising a single strand of spring-like wire having one end formed into a loop 5 and adapted to fit over the nozzle end 6 of a compressible tube 7, the wire extending outwardly from the tube in a horizontal section 8 where the Y same is formed into one or more convolutions as shown at 9'having the plane thereof at right angles with respectvto the plane of the loop 5 and constituting a spring against the compressing action between the section 8 of the wire and the section 10 thereof, which latter extends from the opposite side of the spring in an upwardly inclined direction and. terminates in a loop 11 adapted to engage the upper face of a cap 12, the wire at the completion of the loop 11 being twisted over itself and downward toward the under side of the cap, as at 13, and is then formed into an additional loop 1 1 arranged in vertical alinement with respect to the loops 5 and 11 and adapted to encircle the hub portion 15 of the cap, said loop 14 constituting the termination for the opposite end of the Wire.

It will be seen from an inspection of Figure 2 of the drawing that a plurality of loops are formed from the wire and arranged in vertical alinement and having a spring member interposed between the lower loop and the loop arranged uppermost with respect thereto. i

In this manner the loops 11 and 14 form a grip for the cap whereas the loop 5 forms an attaching means for the neck end of the tube. The spring 9 will yieldably retain the cap in position upon the tube.

It is obvious that the invention issusceptible to various changes and modifications without departing from the spirit or scope of the invention as hereinafter claimed, and I accordingly claim all such forms of the device to which I am entitled.

I claim In a removable cap retainer, a single strand of spring-like wire, having a loop formed at one end adapted to engage the neck of a compres'sible tube, a loop formed intermediate JOHN JosrfPH MoGRAIH.
